虽然目前绝大多数医院都不允许动物入内，但英国皇家护理学院却认为狗狗等动物能够帮助患者康复，应该被允许进入医院。据英媒报道，该机构正在制定相关准则，指导医疗机构安全有效地运用动物疗法，从而使所有患者受益。然而，有学者对该机构的做法表示质疑，认为目前的研究尚不能证明动物对病患的康复起到了作用。 There is no evidence that so-called 'pet-therapy' works, according to a Yale University academic. 耶鲁大学的一项研究称，没有证据表明所谓的“宠物疗法”是行之有效的。 Practices, such as taking dogs on hospital wards, has shown a 'small-to-medium' reduction in patients' distress, found doctoral student Molly Crossman in her review of the medical literature. 博士在读生茉莉•科罗斯曼在其医学文献综述中指出，研究显示，将狗狗带到医院病房的做法对于减轻病患痛苦有“轻微至中度”的效果。 However, she says it's unclear whether the animals deserve the credit as a high number of studies did not control for other possible factors. 但她认为，目前尚不确定这些动物是否真的起到了作用，因为许多研究都没有控制其他的可能因素。 Her comments come as hospitals have been urged to let more dogs and other animals on to wards and even into operating theatres to help patients. |
